Relay in ND mode.
The timer mode can be used to make a short event activate a longer relay output. This can be useful in several
situations where the relay is driving a warning lamp or an acoustic alarm. If the short event happens again after
“Timer min.”, then the sequence will reappear.
Relay in ND mode.
In this example, the event lasts
longer than “Timer Min.”, but it is not longer than the (Timer Min + Timer Max) limit,
so the relay output will be equal to the length of the event.
